is awarded to

Alexandre Blais

"I am honoured and thankful for receiving the 2020 Brockhouse Medal and am I thrilled to be a part of the Canadian physics community. This award would not have been possible without the many talented students, postdocs and collaborators with which I had the privilege of working with over the years." winner citation

The Canadian Association of Physicists (CAP) is pleased to announce that the 2020 CAP/DCMMP Brockhouse Medal is awarded to Alexandre Blais, Université de Sherbrooke, in recognition of for his pioneering contributions to, and continued leadership in, the field of quantum information science. His theoretical research has greatly influenced the forefront experiments in this field. announcement

Professor Blais laid the theoretical foundations of a new field of research known as circuit quantum electrodynamics (circuit QED) that has dramatically changed the field of quantum information.

Quantum information is a new interdisciplinary research area at the interface of quantum physics, computer science and engineering, that promises exponentially more powerful computers than those offered by current technology. However, the development of such a quantum information processing system is a major challenge. Dozens of approaches have been put forward over the past decade, but only a few are now considered realistic and the approach developed by Blais is widely perceived to be the most promising.

Since his appointment at Sherbrooke in 2006, Blais has made several seminal contributions, including the introduction of a new superconducting qubit known as the 'transmon' that is now used by essentially all groups working on superconducting quantum circuits. Recently, he has applied Circuit QED to semiconducting spin qubits, showing that it is possible to develop a semiconductor-based quantum computer architecture with long-range qubit-qubit interactions.

For the past decade, Blais' theoretical work has been guiding experiments in top academic laboratories worldwide (Berkeley, CEA-Saclay, Chicago, Delft, ENS-Paris, ETH Zurich, MIT, Yale). Because it opened new ways of controlling quantum effects in engineered solid-state systems, the far-reaching impact of circuit QED is also felt in a wide range of fields such as quantum optics, atomic physics and mesoscopic physics. Moreover, Circuit QED is now the focus of the quantum computing strategy of major corporations such as Alibaba, Amazon, Google, and IBM. nominator citation
